The incidence of hypothyroidism, for instance, is 0.3–5 cases per 1000 individuals per year, including 7% of women and 3% of men aged 60–89 years. Hypothyroidism is much more common than hyperthyroidism, nodular disease, or thyroid cancer. Thyroid nodules occur in 4–8% of all individuals and, like other thyroid problems, increase in incidence with age.
